R integration

R integration would allow the user to include R code in their Writer document in the same way as one can do today with the '.Rmd' format (R+markdown)and the knitr tool or '.Snw' format (LaTeX + R) and the Sweave tool. The R code could be placed in a similar way inside a 'chunk' as in the aforementioned tools. When you run the chunk you get the figure or table. You can re run the chunk when you want to update the figure or table.
